Johansen-Berg has contributed to understanding of how
stroke impacts the human brain and what rehabilitation strategies can help stroke patients. She published one of the first longitudinal fMRI stroke rehabilitation studies, showing that successful outcomes are associated with increased recruitment of specific motor areas. She also made early contributions to methods for tracing white matter pathways in the brain based on diffusion MRI, in particular developing the concept of a 'connectivity fingerprint' to parcellate neighbouring brain areas based upon their connections to other brain regions. She has been influential in the implementation of these methods in the
FMRIB Software Library (FSL). Her current research focuses on white matter plasticity. Her group provided the first demonstration of white matter plasticity in the human brain; more recently, she has investigated the microstructural basis of this plasticity in rodent models. == References ==
